UNITED STATESA JOSEPH S. DRUMMOND, OF PORT GAMBLE, WASHINGTON.

PENCIL SHARPENER.

Application filed .Tune 4, 1924. Serial No. 717,847.

To all 'willem 'it may concern.'

Be it known that I, JOSEPH S. DRUMMOND, a citizen of the United States, residing at Port Gamble, in the county of Kitsap and State of lVashington, havel invented new and useful Improvements in Pencil Sharpeners, of which the following is a specification.

My invention relates to pencil Sharpeners and has among its objects to provide a pencil Sharpener which will expeditiously sharpen a pencil without chewing or breaking the lead of the same; to provide a. pencil sharpener which will uniformly sharpen or taper the pencil point; and to provide a device which is simple in construction, consists of few parts, and can be manufactured and sold at a minimum cost.

The invention contemplates a rotatable table carrying an abrasive sheet and a holder for supporting the pencil in sharpening position and which is rotated simultaneous with the rotati-on of the table so that the pencil will be sharpened uniformly.

lVith the preceding and other objects and advantages in mind, the invention consists in the novel combination of elements, constructions and arrangement of parts and operation to be hereinafter specifically referred to, claimed and illustrated in the accompanying drawings, wherein:

Figure 1 is a vertical sectional view of a pencil sharpener constructed in accordance with my invention, and

Figure 2 is a. horizontal sectional view taken on line 2-2 of Figure 1.

Referring to the drawings in detail wherein corresponding characters of reference denote corresponding parts throughout the several views, the numeral 5 designates a substantially rectangular casing in which a vertically arranged shaft (i is journaled whose upper endprojects above the upper wall of the casing and carries a turn table or disk 7. Secured to upper face of the disk 7 r by means of pivoted clips `8 is an abrasive sheet l).

Arranged horizontallyT .in the casing 5 is a drive shaft 1() having one end journaled in one of the side walls of the casing 5 and its 50 opposite end journaled in a bearing 11. The

outer end of this drive shaft 10 carries a crank handle 12 while its inner end carries a friction disk 13 which engages a larger friction disk 14 arranged horizontally and fixed to the shaft 6. Supported upon the top wall of the casing 5 adjacent one end thereof is a pulley 15 whose mounting is designated at 16 which is riveted or otherwise secured to the casing 5.

Carried by the pulley mountingl is a pencil receiving tube or guide 17 which is disposed at an oblique angle with respect to the horizontal and overlies the turntable as shown in Figure 1. This guide or tube 17 receives'a pencil designated at P and holds the same at a proper angle for its end to be sharpened. In order to continuously rotate the pencil l? so that it will be sharpened evenly and uniformly an annular bead is formed on the pulley 15 and frictionally engages the pencil. This bead 18 is preferably formed of rubber but any other friction producing material may be employed. A pulley 19 is carried by the shaft 10a-nd engaged about this pulley 19 is a cross belt 2O which is also engaged about the pulley 15.

A substantially rectangulary bottomless hood or protector 21 is removably supported on the upper wall of the casing 5 and is provided with a pencil receiving opening 22 in one of the side walls. This hood or protector 21 is formed of transparent material so that the condition of the pencil end may be determined.

lVhile I have shown and described the preferred embodiment of the invention, it is to be understood that changes in the arrangement of parts may be made and that I am only limited by the appended claim.

Having described the invention, I claim:

A device of the character described, a base, a turn-table supported thereon, an abrasive sheet carried by thek turn-table, a pencil receiving guide disposed at one side of the turn-table, drive means for the turntable including a horizontal shaft, a pulley fixed to the shaft, a second pulley journaled on the base at oneside of the turn-table, an

Vendless belt engaging both pulleys and an annular bead carried by the second mentioned pulley and adapted to engage a pencil to rotate the same simultaneous with the rotation of the turn-table.

In testimony whereof I afxmy signature.

JOSEPH s. DRUMMoND.
